液压支架

液压支架介绍

液压支架是用来控制采煤工作面矿山压力的结构物。采面矿压以外载的形式作用在液压支架上。在液压支架和采面围岩相互作用的力学系统中，若液压支架的各支承件合力与顶板作用在液压支架上的外载合力正好同一直线，则该液压支架对此采面围岩十分适应。

液压支架是综采设备的重要组成部分。它能可靠而有效地支撑和控制工作面的顶板，隔离采空区，防止矸石进入回采工作面和推进输送机。它与采煤机配套使用，实现采煤综合机械化，解决机械化采煤工作中顶板管理落后于采煤工作的矛盾，进一步改善和提高采煤和运输设备的效能，减轻煤矿工人的劳动强度，保障煤矿工人的生命安全。

液压支架的分类

液压支架的类型有很多，按和围岩的相互作用可以分为支撑式，掩护式和支撑掩护式3类；

按移架方式可分为整体自移式和迈步前移式2类；

按使用地点不同分工作面支架和端头支架2类；

按煤层厚度和开采方法不同分为铺联网支架和放顶煤液压支架。
